I too believed the adverts.......should not have done. I had to go over the carpet four times to get all the powder up and the carpet does not look any cleaner. Then I realised my cleaner was red hot, the main filter was completely blocked with the powder and the other filter was so hot it almost burnt me when I touched it. If I had carried on using the machine it may well have gone on fire. I am normally very happy with Vanish products and was disappointed that this did not come up to their usual standard.
